OSCommerce attribute fixes (OsCommerce, PHP)

Changes on the page

http://www. y o u r a r t n o w.com/index.php?cName=all

1. List just 4 products instead of 16,make size one of the options listed with subjects and frames

2. in the product detail page, add option and make option interactive

for example

http://www.y o u r a r t n o w.com/product_info.php?pName=oil-painting-20-x-24

make size the first option
Prices on different sized should be actural prices instead of prices added . I already installed a contribution , hope it helps

make the subject as the second option, however, if the different sizes are selected, subject prices also needs to be changed. the same as the frame options. change according to the sizes

3. Want to get it done as soon as possible, with minimum customer impact, preferebly in non business hours for US times, backup please.

sent me some samples and portfolios
